The concomitant symptoms of sacroiliac joint pain vary depending on the primary disease.
Patients with fractures and dislocations of the sacroiliac region due to trauma are often associated with subcutaneous bruising and injuries to other parts of the pelvis; patients with tuberculosis of the sacroiliac joint are associated with low-grade fever, general malaise, night sweats, weight loss, loss of appetite, pressure pain and swelling at the sacroiliac joint, positive pelvic compression and separation tests and the ‘4’ test; patients with tumours are often associated with fever. Patients with tumours often have symptoms such as masses, general weakness, loss of appetite and nerve paralysis.
